Note no. 1.
Give others a break will you ? Atleast dont make their life harder than it already is.. you are not the only one who is grieving and you are not perfect Neither are others! Deal with it. Dont expect too much!
Note no. 2.
Its about time you changed jobs as you have been bored for a long time now. And if you cannot change your job(if you are too lazy!!) you better buck up and atleast do the job you have sincerely. It is sickly how you no longer have pride in helping people.
Note no. 3.
You have closed yourself to life experiences. It is not that adventures no longer happen to you. Its just that you have closed your eyes to them. And even if you notice them, the humor is lost to you. Lighten up.
Note no. 4.
Its healthy to accept that you are wrong when you are wrong. Easier said than done though. This twisted lil ego that you have needs spanking.
